AUTOMOBILE-BUFFER.

Application filed June 11, 1920, Serial No. 388,321.

To all whom it may concern mobiles.

The object of my present invention being to improve and cheapen the construction of the impact receiving member of the buffer and the means for attaching the buffer to an automobile, together with such other elements and combinations as are hereinafter more particularly set forth and subsequently claimed.

The mannerin which I attain myob'jects is illustrated in the accompanying in which:

Figure I. is a plan view of my improved Fig. II. is a rear elevation of Fig. I.

Fig. III. is a front. elevation of the buffer. Fig. IV 15 aside elevation of my improved bufier on'a large scale and illustrates the adilistable ataching means.

Fig. V.-is an. enlarged detail along line 5-5 on Fig. I.

The same reference letters refer to the same parts throughout-the several views.

g The buffer and attaching means here illustrated are an improvement on-the automobile buifer previously invented by, and for ox was granted U. S. said patent bearing the number 1,385,877.

Refeiring to the drawings, A, is a resilient impact receiving member, made from a single piece of material, looped as shown, so

that the ends come together at or near the center of the front bar of the loop.' The free ends of the looped members are then joined together by means of the reinforcing strip B, which is preferably attached thereto by means of suitable bolts and nuts, N. N.

A clip member E, adapted to closely fit against one side and both edges of the looped ofthe looped member meet. A suitable bolt L, passing through the reinforcing strip B, between the ends of the looped member A,

and through the clip member E, co-acts with a nut Q, and joins the whole securely together 1 n a neat manner. A/lock-washer 'P, is prov1ded to prevent accidental loosening of the nut O, and similar ock -washers are preferably provided uniVll nuts used with the devlce.

impact receiving member A. Slotted openmgsc, 0, provide means'whereby' the supporting members may beadjusted to fit various wldths of frames. Suitable bolts and nuts M, M, are used to attach the impact receiving member to members. Adjustably attached to'the ends of the supporting members C, C, are-the attachment plates D, D. The attachment plate D, 1s provided with a slotted opening d, and the end of the supporting memberis preferably provided with two holes. A bolt and nut H (with a suitable lock-washer) are used to fasten the attachment plate to the end of the supporting member. The side of the attachment plate D, adapted to contact with the automobile frame K, is recessed so as to receive the headof the bolt H, as indicated In Figs. I and IV.

the supporting A hook bolt F, extending through asupone flange of the side bar K, of an automobile frame.

A similar hook-bolt G, extend-. ing through the opposite end of the attachment plate, is adapted to enga e with the opposite flange of the side bar See Figs. I, II and IV.

In the previouspatent before referred to, the impact receiving member was a continuous loop, the front bar arched to add strength. e y

This member was made by looping a piece of high grade carbonsteel and welding the ends together. v

My improved buffer has a loop of substan tially the same shape, but instead of Welding so as to form a continuous loop, the

30int is made by bolting a strap to the abuttmg ends, and covering the point with The additional strap-makes an effective 'c'ost'of making a suitable weld in the class of material' used.

2. In an automobile buffer, an impact receiving member comprising a single piece of flat spring material formed into an elongated loop haying rounded ends slightly curred in the plane of the loop sides and a reinforcing strap joiningthe free ends of said loop; means for mounting said impact receiving member on an automobileso that both bars of the looped member thereof lie in a substantially horizontal plane across the end and in front of said automobile and parallel to the axles thereof? In an automobile buffer, an impact receiving member comprising a single piece of flat spring'nniterial formed into an elongated loo'p having rounded ends slightly curved in the plane of the loop sides. and

a reinforcing strap joining the freeends of' said loop; rearwardlv extending supporting members ad ustably connected to said impact receiving member; and means tor ."i'iimovably attaching said supporting members to the side bars of an automobile frame.

4. In an autonmbile buffer, an impact receiving member comprising a single piece of flat spring material formed into an elongated loop having rounded ends slightlycurved in the plane of the loop sides, and a reinforcing strap joining the free endsol' said loop; curved rearwardly extending resilient supporting members adjustably attached to said impact receiving member; and

means for removably and adjustably attaching said supporting members to the of an automobile frame.

5. In an automobile butfer, an impact receiving member comprising a single piece of flat spring material formed into an elonside bars gated loop having rounded ends slightly curved in the plane of the loop sides, and'a reinforcing strap joining thefree ends of saidloop; curved rearwardly extending re.

silient supporting members adjustably attached to said impact receiving member, attachment plates adjustablyattachedto the endsof said supportingmembers; a hook bolt extending through said supportii'ig member and one end of said attachment plate, the hook end thereof adapted to engage with one of the'flanges on a channeled side bar of an automobile"framesa hookbolt extendingdlirough the other end of said attachment plate the hook end thereof adapted to engage with the other flange on said side bar; and nuts co actiiig with said hook; bolts to clamp said attachment plates and said supporting members ;$P(:lll8l;\' to the side bar of an automobile franief.
